Abstract：

0.30Pb(Lu1/2Nb1/2)O3-xPb(Ni1/3Nb2/3)O3-(0.70-x)PbTiO3(PLN-PNN-PT)　ceramics　with　various　PNN　contents　were　prepared　using　a　modified　two-step　columbite　precursor　method　and　characterized　by　X-ray　diffraction　(XRD),　ferroelectric　and　dielectric　measurements.　The　composition　of　0.30PLN-0.31PNN-0.39PT　exhibits　excellent　physical　properties　with　d33 = 366pC/N,　TC = 214 °C,　ε′ = 3076,　tan　δ = 0.0225,　Pr = 32.89μC/cm2and　Ec = 15.23KV/cm.　The　values　of　relaxor　factor　γ　approaches　2　indicating　diffuse　character　of　PLN-PNN-PT　ceramic.　The　dielectric　behavior　was　discussed　based　on　Curie-Weiss　Law　and　Lorentz-type　quadratic　relationship.　A　transformation　from　relaxor　ferroelectric　to　normal　ferroelectric　was　demonstrated　with　PT　content　increasing　in　this　ternary　system.　©　2017　Elsevier　B.V.
